To find the speed of the bobsled, you divide the distance by time. So, when you divide 106 by 26, you get 4.07. This means the speed of the bobsled is about 4 miles per hour.

a body thrown vertically upwards from grounf with inital vel 40m/s then time taken by it to reach max hieght is?

777dan777 [17]

Answer:

t = 4.08 s

Explanation:

if the body is thrown upward, it has negative gravity. Knowing through the International System that the earth's gravity is 9.8 m/s²

Data:

Vo = 40 m/s
g = -9.8 m/s²
t = ?

Use formula:

$\boxed{\bold{t=\frac{-(V_{0})}{g}}}$

Replace and solve:

$\boxed{\bold{t=\frac{-(40\frac{m}{s})}{-9.8\frac{m}{s^{2}}}}}$

$\boxed{\boxed{\bold{t=4.08\ s}}}$

Time taken by it to reach max height is <u>4.08 seconds.</u>

Greetings.
